ForkLift is a powerful file manager and ferociously fast FTP client clothed in a clean and versatile UI that offers the combination of absolute simplicity and raw power expected from a well-executed Mac software.

ForkLift will connect to any remote server FTP, SFTP, Amazon S3, WebDAV, the SMB, NIS and AFP shares on your local network, or your Bluetooth mobile phone- pretty much anything you can plug into or hook up to a Mac. ForkLift also carries a complete toolbox for managing your files, including Folder Synchronization, Batch Renaming, Archive handling, Application deleter, editing files over remote connections and many more. All these power features are packaged into a Finder-like, dual-pane interface that delivers superior workflow while remaining absolutely familiar to use, along with QuickLook, Spotlight search and all.

Its a fantastic application.
But would the devs please, PLLLEAAAASE THINK ABOUT USING AN OTHER PAYMENT METHOD so you don't have to register a CRAPPY PAYPAL account for getting a license of this wonderful app?!
Thanks...

Installed trial, moved just a few files around my HDD and to FTP and instantly knew I had to have it.

Just taken them up on the 47% off deal with only 6 hours remaining. I must say it feels like I just found Â£10 on the floor and bought a gold watch with it. Can't wait for this to get better and better - as long as it doesn't get 'top heavy' like pathfinder as I quite agree with astorgs comment

This has to be the best application I have seen this year. It completely replaces no less than three applications that I previously used daily: PathFinder (which had been getting a bit top-heavy recently); Transmit (the FTP in Forklift supports SFTP, like Transmit, but is actually much more intuitive and easy to use); and AppZapper (you can delete applications safely from inside the panel).

No way is Amazon S3 the cheapest backup service available -- Mozy.com has got to be the cheapest at $5 a month for unlimited storage and bandwidth. (That said, Mozy's performance is probably nowhere near Amazon's -- S3 is designed as a transactional file system where the data is going in and out constantly, whereas Mozy is meant as a file storage repository). But still... :-)
